The Slammer tips the scales at 615 grams and you feel every ounce of that weight while smoothly shifting from gear to gear. The mass of the Slammer helps redefine your shifting experience by allowing the weight of the knob to work in your favor while slamming gears.

Well, to put it as simply as we can, the heavier the knob, the easier it will make shifting feel. Its not magic, its physics. Weight in motion directly relates to how an object will react to an opposing force. In this case, the opposing force is the gate pattern and counter springs that are connected to your shift arm that tell you the shift pattern of your car. The difference felt when shifting into the next gear requires far less effort due to the additional momentum created by the increased mass.


A shift knob is one of the most touched accessories in the car, short of the steering wheel and pedals. We designed the Slammer to be just as aesthetically pleasing as it is to hold in the palm of your hand.

The shape of the Slammer is not the traditional ball shaped shift knob for a reason. The ergonomics behind an overhand grip shift position require a full form shape at the bottom and a flatter top shape to fill your palm. The combination of these elements drove the shape of the Slammer.


The Slammer is CNC machined from 303 stainless steel. Machining stainless steel is not an easy task. It requires close supervision of their CNC turning centers and tooling to ensure a flawless part and surface finish.


This translucent finish is unique and high quality.


The Slammer shift knob will come with a billet aluminum threaded adapter with a M12 x 1.25mm thread to fit the shift knob to your WRX / STI / BRZ shifter arm


A set screw is also included that allows you to easily adjust the orientation of the shift gate pattern and the height of the shift knob. Instructions are included to help you thru the installation process.
